What is the treatment for a foot blister?

Blisters commonly heal on their own, but treatments such as covering the blister with a loose bandage or draining the blister can help enhance healing, prevent infection and decrease pain, explains WebMD. Torn or drained blisters on the foot area should be cleaned with soap and water.

Patients should apply antibiotic ointment to torn or drained blisters after cleaning and before covering with a loose bandage, according to WebMD. Dirt, bacteria and grime can increase the risk of infection. Patients should avoid using iodine or alcohol on the affected area. People with medical conditions who develop a blister should consult with their physician regarding treatment.
